Serial No. 482,995.

This invention relatesto filling replenishing looms wherein the illingischanged from V'time to time either by thesubstitution of a fresh shuttlefor that which has become depleted or by a change of the filling carrierin the shuttle for a freshV filling carrier.

Infilling replenishing looms it is desirable thattheoutgoing andincoming iillingend be parted at ther replenishing side of the loom andthat incase the filling fails at this point the lloom be stopped.

Y Y Heretofore it has been common to provide .f filling or weft forkmechanisms to stop the loom in case of filling failure, and also to cutor part the incoming and outgoing filling Yends.V In looms for weft pilefabrics, however, where the ends of the pile wires extend `beyond theedge or selvage of the Cloth and are "accumulated in this position for anumber of picks, the Vproblem ofv effecting'the foregoingdesirable'results becomes complicated,fand-one of the objects of thepresent invention is to provide means forefecting loom stoppage throughthe filling fork when filling-failsto be laid in theshed and to cutorpart the filling vends at the side of the yloom yadjacent thereplenishing mechanism; 7

More specifically stated, the weft fork actuating slide and thelcuttingor parting mechanism are each actuated bya novel train ofdevicesdisposed at the,filling-replenishing t side of lthe loom andadapted to be operated through or by the lay movements.

The invention and novel features thereof `will .best be maderclear fromthe following description and the accompanying drawings of one good formthereof,

In the drawings: i K' VIligl is a perspective view of parts of a shuttlereplenishing loom provided with the features of the present inventionFig.f2 is a vertical sectional view through they filling fork mechanism;

The features of the present invention have been lllustrated inconnection with a pile vfabric loom provided with shuttle transfer`mechanism similar to that more fully shown and described in the EdwinW. Stone application, SerialNo. 481,841 filed Sept..15, 1930. The loomshown has the breast beam or supporting structure l in front of whichVisV disposed the usual take-up roll 2 about which the woven fabric F isadvanced during the weaving operation, in a well-known manner.

The loom is also provided with the usual lay 3 supported by the layswords 4 for move#` ment towards and from the frontof the loom and thelay is provided with the reed 5 which is supported at its upper end bythe reed cap 6, the opposite ends of this reed cap being `secured to theextensions 7 provided at thel upper ends of the lay swords.v

At theleft-hand side of thel'loom illustrated'in Fig. 1 is provided 'theshuttle replenishing mechanism comprising the shuttle magazine 8 whichis adjustably supported... Vby the bracket 9 secured to the loom frame.

` Thel shuttle box at the rear of the shuttle maga-zine 8 is shown ashaving a movable front wallv 10 adapted to be carried upwardly by thesupporting arms 11 in a manner la pile fabric and is shown as providedwith pilewires 13, the forward ends of which are `shown in Fig. 3 asextending some distance rfrom the selvage at the left-hand side of thethe lay of the loom of Fig. 1, looking towards abrlc The vfeatures sofar described form no essential part of the present invention but havebeenk illustrated and briefly set forth to makeV clear the constructionand location -of the filling fork and shear mechanism to be described,and the novel mechanism of the ,present invention for imparting adetecting movement to the slide operating lever kand for operating theshear blade. The filling fork mechanism illustrated comprises atrough-shaped stand 14 which is rigidly se-V cured to the breast beam ormain frame of the loom in position tofclear-.theends- 1 3 of the lpilewires; as shown,.land :in'thisgstand is slidably mounted the iillingforlr slide 15.z

In accordance with the present invention, 1the-means for moving thefilling forkV slide 'frontwardly Awhen an absence fof filling isvdetected comprises a slide operating lever '28, the lower end of whichis pivotally sup- `portedibythefpin'29 carried by the bracket or housingB0-secured to the loom-frame,v and the lever-528 iscontinuously-urgedtowards the dotted line position of Fig. 2 by thecoiled spring 31.v The lever 28 is shown as having ahead or 'enlargementat its Aupper endy and this head [is provided iwith Va .shoulder 32adapted togengage the .looped `portieri 18 .of .the fillingjforkwhenthelatter remains .the lowered position of. l`|`i g.s4, .uponadete'cting beat ofthe .lever.-28.

Therod 46'eXtends'through ahole 48`inthe`plu-nger42. The arrangement is such that'theLplunger .42- may bero'clred in either an upwar'd'or 'aidownward direction from its@normally horizolitalposition vbut as soon as theplimgeris releasedvitwillfberepanding-actiono-f'the springs45.; v

prior formsfofoperating meansbysernplfyf yinactive position during onebeat-up movement of the lay but is moved frontwardly upon the nextbeat-up movement of the lay and remains in this frontward position untilthe operating cam 37 is again rocked in a downward direction so that thelever 28 may ret-urn to its rearward position under the. ac-

tion of the spring 31.

It will be seen from the foregoing that the plunger 42 operates the cams37 and 39 so that they will impart a detecting beat to the lever 28 onlyupon every other frontward movementof the lay, and as a result thefilling fork slide will be forced frontwardly only Awhen thefshuttle isin the left-hand box, viewing Fig. 1, and the filling fails to tilt thefilling yfork sufficiently to clear the shoulder 32 of the slideoperating lever.

Itis apparent that when filling replenishment is effected, a trailingend of filling will 'be formed extending from the cloth selvage.

In the construction shown,itwo of these trailing ends are formed, one bythe ejected exhausted shuttle and the other by the new shuttle. It isdesirable to part these trailing ends so that they will not be carriedinto the 'n shed, and shearing means to this end may comprise a fixedshear blade 49 rigidly secured to the stand 14 and a movable shear blade50 supported by the pivotal pin 51, and the movable blade 50 ispreferably yieldingly held against the fixed blade by the coiled spring52 provided upon the pin 51 between the movable blade and nuts 53.

The movable shear blade 50 is actuated in accordance with the presentinvention from the rocking shaft 38, and to this end the shaft 38 isprovided with an actuating arm 54 which is operatively connected to therear` end portion of the blade 50 by the connecting link 55. Thearrangement is such that one beatup movement of the lay will rock theshaft 38 in a direction to open the shear blade 50 and the. next beat-upmovement of the lay will close this shear blade to clip the trailingfilling, provided the same has been advanced frontwardly by the fabric Fbetween the blades 49 and 50.

The coiled spring 52 serves to create sufficient friction between thecooperating blades 49 and 50 to cause the blade 5() to remain in eitherits open or closed position until it is positively shifted from suchposition by the ytion'the forward movement of the lay is utilplunger 42upon the. next forward-movement of the lay.

f It will be seen from the foregoing that through the mechanism of thepresent invenized to operate both the slide operating lever and fillingshearing mechanism, and that the mechanism for operating these elementsis simple in construction and reliable in operation.
